Does anyone know what Litetouch/Savant uses for communication between the controller and keypads/modules? I'm guessing it's RS-485. Also, is the protocol they use over it documented anywhere?
I have an aging Litetouch system, and I was going to experiment with an Arduino touchscreen to see how tough it would be to replace the keypads with something a bit more modern looking.
